The engine has now been bolted on the frame with the diff all lined up.
Chain was fitted and clears the engine casing :)
Engine now put away as its not needed till its fitted into the car.

Frame has been put into the car and fits OK :wink:
I won't weld anything to the shell so it can be put back if many many years in the future someone wanted to convert the car back to original.

There is not a chance ever ever ever that I will want the original engine back in the car :wink:
In fact I'm going to have a big clear out in the spring of all the Stiletto bits I have like engine, gearbox and interior.
They can all go on Ebay as I will never want them.
The car will look original apart from the colour and non vinyl roof, but the GO will defiantly be not.
I was going to go plastic windows etc to save weight, but as the car is so rare I will for the time being leave it alone.
Just disk brakes, Monte springs, a roll cage and Recaro seats giving the game away.
Oh and air vents on the bonnet.

Looking forward to the Classic day at Castle Combe, where I hope to be out on track lots :D

That's very neat! :mrgreen: I too take my hat off to you for seeing the project through thus far and for not hacking the car about too much at all in your search for bike power for your Stiletto. 8) Well done!

Thanks :D

When I'm happy with the frame and I'm certain it all fits and works.
I will post dimensions for the frame and how I fitted it plus contact details of the parts suppliers I have used.

I'm currently looking at sub £1.5k including buying the car :o
When I start selling some of the original Stiletto bits I should off set that too ££ :wink:

A productive day
Frame is now bolted in the car and fits really well.
The diff is bolted to it and I have had the drive shafts connected up.
Due to the Imp shaft knuckles fouling the joint when the suspension is on its limit of travel up I have removed the shafts from the hubs for a little bit of "fettling" with an air grinder.

A hell of a job to get the hub nuts off and shafts out....
An air impact gun and oxy acetylene on the nuts.
But job done.

I will get a few pictures on Friday when I'm next at the workshop.

No pictures today as I ran out of time.
But drive shafts have been modified and cleaned up.
Spoken to Malcolm and ordered some bits I need.
Noticed one of the hub nuts thread had shattered when we undid it. It was murderously tight. So contacted Malcolm for another .

Phoned Gaz suspension and ordered a pair of front shocks. Adjustable and shortened for Monte springs. £158 a pair delivered :)

Also just bought a brand new Sunbeam badge off Ebay for the front for £15 ...well chuffed.

Carefully use the other hub nut to check the thread on the shaft. No good putting a new nut on if the thread is damaged.

A few issues with the drive shaft knuckles binding due to the angle they are at.

I'm going to grind hollows on the knuckles. But if that does not allow enough movement I can move the whole frame forward slightly.
Problem then is the engine and exhaust are VERY close to the back of my very nice Recaro seats.

Heat proof wrapped manifold will be a must :lol:

The frame is pretty sturdy, 40mm thick walled box section.

Thanks :)

4 packages arrived the other day with Malcolm Anderson Imp spares label on 2 of them.
The others were a brand new Sunbeam badge and 8 Silicon rubber 90 deg hose bends.
I hope to have the drive shafts all fitted and the engine in place before Christmas
Think I had better pull my finger out as I only have 10 days to go !

Must say looking at this project I wish I would have just bought a bike engine for my imp rather than doing 2k+ on modding an engine I doubt will see the naughty side of 75bhp :lol: anyone want to buy an expensive non impressive engine? :lol:

Looking great, keep up the good work :)

I have just listed the Classic & Retro Sporting Car action day on another club I belong to Forum.
There is always a few representatives of the Imp club there.

If you come along Basil Imp, bring a crash helmet, I'm intending to be out on track for a couple of sessions having some fun in my 908cc Sunbeam Stiletto
Chrome gleaming and looking original and 125bhp to play with :wink:

That's progressing nicely. :) What are you going to use to protect the metal of the differential carrying frame that you have constructed?

I have some galvanize spray paint, then it will be Ford Rosso Red.
I have 7 litres of the stuff to paint the car inside and out. :lol:
Think I should get good coverage with that...

I have just about given up saving weight, and have decided a plumbed in Fire extinguisher is required.
The seats will be around 4" away from the exhaust so things could get a bit hot.
Strength and safety are nearing the top of my list now. :wink:

Had a very productive time working on the Stiletto today.

I wasn't happy with the angle of the diff's drive shafts joints at full extension. so I unbolted the frame and moved it forward by 40mm and dropped the diff end by the same amount.
Now bolted up tightly, hub nuts all torqued up and wheels refitted.
(Thanks Malcolm I found the studs you sent in with the trim clips) :)
Drive shafts have plenty of movement for the suspension travel.
I need to weld in a couple of plates where I cut away some of the rear panel with no need.
Then its engine in and see where the water pipes need to go.

Really getting there now :wink:

Gaz adjustable shocks arrived this morning :) Will be one of the last things to fit before its MOT though.
I don't want to get over spray over the nickel plating and spoil them.

Hard front, soft back suspension I think, before anyone says thats not how to set an Imp up.
Remember my engine is mid mounted, there is no weight really from the back of the rear seat backwards.
It will be fun setting it up on a empty airfield runway :lol:

Even so, a hard front /soft rear sounds like a recipe for terminal understeer? :o

At least there are no corners on an empty airfield runway ... :wink:

Would still expect a softer front seeing it's a mid-rear engined set-up -otherwise turn-in would be adversely affected?
Where is the weight transfer coming from at the front on turn-in?
Maybe I'm missing something obvious - so what's your reasoning for a hard front?

Must confess I was thinking the same. Even down to porsche boxsters rear springs are relitivley strong compared to the front springs. I would still expect it to be the rears would be stiffer, just not to the same extent as imps are as standard. I think imp race springs are roughly 200 ish lbs on the front and 800 rears? (It is 3:30 am whilst writing this so I may be wrong :lol: so I would be tempted to keep the front springs sround that sort if area (maybe even increase to 225/250 or maybe even more lbs than that, and then drop the rears into the 6/700lbs area?


If not great laugh setting it up :lol: , keep us updated anyway, be interesting to see :D

My only real experience is setting up Escorts to handle, so the Stiletto will be a venture into the unknown.
But from them I know if I have the front soft and the back hard, the car will tend to compress the front corner under load and try and lift a back wheel off the floor, unloading. Likely to spin it up if I have any power on.
Through geometry, tyres, weight and splitter I want the front level and a tendency to over steer.
I want the back sinking down hard with both wheels in contact with the floor.

Re: Sunbeam Stiletto with a Kawaski Engine.

A FERWD Escort already has major mass at the front so it does make sense to harden the front.

But driving a mid-engined or rear engined car calls for a different driving technique - you won't be driving it like an RWD Escort
(or a FWD puma).

First lesson with a Mid/rear RWD car is not lift but keep your foot-in (to varying degrees) during cornering!

...which keeps a rear-biased RWD car settled and all ready to squirt up the road after apexing.

...also in slower corners timely braking gets rear weight transfer forward for front end to turn-in but if you harden the front too much it will resist the weight transfer and understeer into slow corners is guaranteed.

Quite a productive day again.
Removed all the sound deadening bitumen panels and all the foam which was stuck to the roof. (Head lining)
Welded the angle iron across the top of what was the back seat back and welded plates in to cover up some of the unnecessary holes in the rear fire wall.
I "Think" all the structural repair welding is done :)
Image

Car is now externally in primer .
Image

The engine is now fitted but only on the front mounts as some of the floor needs removing as the engine now sits so low. to
Need to get my reciprocating air saw on the job.

Thats it for a week or so.

The car's looking good, Graham. 8)

If it were mine, I'd consider a semi-continuous seam weld (an inch of weld, two inches of gap to the next weld, and so on...) to the angle iron structural member between the shock absorber mounts, rather than some more localised lap welds. Just a thought. It's tricky to tell from your photo. :wink:

It's going to be a beast! :twisted:

It quite a meaty bit of angle Iron and its really only welded at the ends, there are a few bits of weld here the sheet is close.
Its actually there for top engine brace bars from the front of the cylinder head backwards.
There will be a full cage going in too, so the shell should be pretty strong.

Next week or the week, after when I'm free to do some more work, I should the the engine bolted properly in place and some paint splashed around where the engine is.

A Beast, hopefully in sheeps clothing, as I'm trying to keep it looking pretty original from the outside.
The exhaust note will be the give away :lol:

Popped into the workshop today and was surprised to see the car in colour.
My mate had been busy, cutting away for the engine to sit in the void under the rear seat and giving the car a couple of preliminary coats and Ford Rosso Red.

I need to remove a little bit more under the engine and make a hole for the oil drain.
Then add some angle / box section to regain the strength lost by cutting away.
It's Getting there though :D

Interesting project really. Looking good.
I'm not a big fan of bike engine "conversions" but this one appears to have some thinking put into it, not just optimism and hopes.
Keep the posts coming please. Want to know everything about it, it might come to good use if I win the lottery. :D

Being an engineer does help, and I spent quite a lot of my youth putting bigger engines into Ford Escorts. :wink:
Plus the two friends who own the workshop where the car is have spent a a good 40 years working on classic cars.

They are enjoying the challenge as much as me :lol:

I will have a tot up of the £'s in the end, but I will be surprised if I exceed £1500 including buying the car :shock:
I can off set quite a bit when I start selling the two engines, carbs, radiator, gearbox, interior etc etc I have in the shed.

Spent a day on the Stiletto today, Engine now clear of the floor and fixings line up ok.
Image
We beefed up the rear suspension mounts with some heavy gauge angle iron, to replace any strength lost but cutting the floor.

Also cut the bonnet and fitted the RS Turbo vents.
Need to fit some ducting to direct the air at somepoint.
Image

Window winder un-seized and the door locking mechanism refitted.
Window now goes up and down and door will latch closed.

Next is weld up under the engine to make a bit neater and splash some paint.
Then fit the oil cooler and cooling pipes to the engine.
I "think" there is plenty of room for the pipes and gear linkage with whats cut away already.

NIce job! Don't know how I missed this thread. Great to see someone go ahead with something like this rather than either give up or get put off by the negativity quite often given about bike engine car projects. Would love to have something like this myself.

Er, I think you've put the engine in upside down, Graham. :P

As per what Pete said, it's great to see someone with the commitment carry off a bike engine conversion. 8) It has happened before but all too often people get cold feet when they hit trouble. Credit to you, Graham, for sticking at it. It will be awesome when it's done - and quite the track day weapon too! :mrgreen:

Wow, tilting the engine to get at the chain drive. Does it also help with draining the sump?

Jesting apart - I agree with the others. Well done on sticking with the project and overcoming the issues.. I am guessing you started this knowing exactly what was required in terms of ability and committment. Well done. Keep the updates coming.

I had a long hard think of what I wanted from the car.
A car I can drive to shows and display occasionally, not very fast but handled well.
Or a car which would raise the pulse rate and put a grin on my face.

You can guess which won :D

Can't wait to drive it, I grew up on RWD and have raced "This" Stiletto before many many years ago.


Looking reasonably original and going like F..k is the aim. :lol:

It was handy having the engine on its front mounts and being able just to flip it over to check the "fit".
